Inheritance diagram for Lucene::LengthFilter:Public Member Functions | |
| LengthFilter (TokenStreamPtr input, int32_t min, int32_t max) | |
| Build a filter that removes words that are too long or too short from the text. More... | |
| virtual | ~LengthFilter () |
| virtual String | getClassName () |
| boost::shared_ptr< LengthFilter > | shared_from_this () |
| virtual bool | incrementToken () |
| Returns the next input Token whose term() is the right len. More... | |
| Public Member Functions inherited from Lucene::TokenFilter | |
| virtual | ~TokenFilter () |
| boost::shared_ptr< TokenFilter > | shared_from_this () |
| virtual void | end () |
| Performs end-of-stream operations, if any, and calls then end() on the input TokenStream. NOTE: Be sure to call TokenFilter::end() first when overriding this method. More... | |
| virtual void | close () |
| Close the input TokenStream. More... | |
| virtual void | reset () |
| Reset the filter as well as the input TokenStream. More... | |
| Public Member Functions inherited from Lucene::TokenStream | |
| virtual | ~TokenStream () |
| boost::shared_ptr< TokenStream > | shared_from_this () |
| Public Member Functions inherited from Lucene::AttributeSource | |
| AttributeSource () | |
| An AttributeSource using the default attribute factory DefaultAttributeFactory. More... | |
| AttributeSource (AttributeSourcePtr input) | |
| An AttributeSource that uses the same attributes as the supplied one. More... | |
| AttributeSource (AttributeFactoryPtr factory) | |
| An AttributeSource using the supplied AttributeFactory for creating new Attribute instances. More... | |
| virtual | ~AttributeSource () |
| boost::shared_ptr < AttributeSource > | shared_from_this () |
| AttributeFactoryPtr | getAttributeFactory () |
| returns the used AttributeFactory. More... | |
| template<class ATTR > | |
| boost::shared_ptr< ATTR > | addAttribute () |
| This method first checks if an instance of that class is already in this AttributeSource and returns it. Otherwise a new instance is created, added to this AttributeSource and returned. More... | |
| void | addAttribute (const String &className, AttributePtr attrImpl) |
| Adds a custom Attribute instance. More... | |
| bool | hasAttributes () |
| Returns true if this AttributeSource has any attributes. More... | |
| template<class ATTR > | |
| bool | hasAttribute () |
| Returns true, if this AttributeSource contains the passed-in Attribute. More... | |
| template<class ATTR > | |
| boost::shared_ptr< ATTR > | getAttribute () |
| Returns the instance of the passed in Attribute contained in this AttributeSource. More... | |
| void | clearAttributes () |
| Resets all Attributes in this AttributeSource by calling AttributeImpl#clear() on each Attribute implementation. More... | |
| AttributeSourceStatePtr | captureState () |
| Captures the state of all Attributes. The return value can be passed to restoreState to restore the state of this or another AttributeSource. More... | |
| void | restoreState (AttributeSourceStatePtr state) |
| Restores this state by copying the values of all attribute implementations that this state contains into the attributes implementations of the targetStream. The targetStream must contain a corresponding instance for each argument contained in this state (eg. it is not possible to restore the state of an AttributeSource containing a TermAttribute into a AttributeSource using a Token instance as implementation). More... | |
| virtual int32_t | hashCode () |
| Return hash code for this object. More... | |
| virtual bool | equals (LuceneObjectPtr other) |
| Return whether two objects are equal. More... | |
| virtual String | toString () |
| Returns a string representation of the object. More... | |
| AttributeSourcePtr | cloneAttributes () |
| Performs a clone of all AttributeImpl instances returned in a new AttributeSource instance. This method can be used to eg. create another TokenStream with exactly the same attributes (using AttributeSource(AttributeSource)) More... | |
| Collection< AttributePtr > | getAttributes () |
| Return a vector of attributes based on currentState. More... | |
| Public Member Functions inherited from Lucene::LuceneObject | |
| virtual | ~LuceneObject () |
| virtual void | initialize () |
| Called directly after instantiation to create objects that depend on this object being fully constructed. More... | |
| virtual LuceneObjectPtr | clone (LuceneObjectPtr other=LuceneObjectPtr()) |
| Return clone of this object. More... | |
| virtual int32_t | compareTo (LuceneObjectPtr other) |
| Compare two objects. More... | |
| Public Member Functions inherited from Lucene::LuceneSync | |
| virtual | ~LuceneSync () |
| virtual SynchronizePtr | getSync () |
| Return this object synchronize lock. More... | |
| virtual LuceneSignalPtr | getSignal () |
| Return this object signal. More... | |
| virtual void | lock (int32_t timeout=0) |
| Lock this object using an optional timeout. More... | |
| virtual void | unlock () |
| Unlock this object. More... | |
| virtual bool | holdsLock () |
| Returns true if this object is currently locked by current thread. More... | |
| virtual void | wait (int32_t timeout=0) |
| Wait for signal using an optional timeout. More... | |
| virtual void | notifyAll () |
| Notify all threads waiting for signal. More... | |
